OAKLAND, Calif. — Philip Rivers and the San Diego Chargers capitalized on mistakes instead of making them for a change.

Rivers threw a 6-yard touchdown pass to Malcom Floyd and Nate Kaeding kicked five field goals to spoil Dennis Allen’s debut as Oakland coach by beating the Raiders 22-14 on Monday night.

“I’ve always tried to take care of the football and be smart but you have to be able to manage the situation,” Rivers said. “The situation today was our defense was playing good, our special teams is getting the ball. ... If you go back since I’ve been playing here and we don’t turn the ball over, it’s 90-something percent we win. That was the key for the offense tonight.”

The Raiders were looking to start a new era on a positive note but were done in by an offense that couldn’t score a touchdown until the final minute and three botched punts after an injury to Pro Bowl long snapper Jon Condo.
